Having issues with my stand up Dukers freezer

I’ve pulled it pretty much apart and what I found is that the fan just doesn’t run sometimes, which leads to freezing up and not getting cold enough. The fan isn’t damaged. It still spins, but sometimes it just randomly stops and doesn’t turn back on. The fan also isn’t freezing. I tested it while having the freezer door open and it did not spin. The only part that I’ve found that could possibly be the problem is the power cord, since it gets smooshed against the door when it opens. If anyone has had similar issues let me know
